This study was performed to analyze the relationship among sebum hydration content of the skin and nutritional intake, serum antioxidant minerals and antioxidant enzymes, and lipid peroxide concentration in 50 female subjects in their 20s. The skin type was divided into Dry Skin, Mixed Skin, and Oily Skin, and the dry skin group was 14%, the mixed skin group was 56%, and the oily skin group was 30% of all subjects. The average age of the subjects was $20.54{\pm}1.43$ years and BMI was 20.66. The average sebum content in each group was in the order of T-zone>forehead>chin>cheek. In case of the T-zone, a significant difference between the dry skin group and the oily skin group was observed, suggesting that the area is most sensitive to sebum content by skin type. Significant differences were not observed in energy and nutrient intakes by skin type. Serum concentrations of antioxidant minerals such as copper, manganese, zinc and selenium were not significantly different among the groups, but the dry skin group tended to be higher than the oily skin group. Serum catalase was significantly higher in the oily skin group (P < 0.05), and MDA was significantly higher in the mixed skin group (P < 0.05). The hydration of the cheek and serum zinc showed a negative correlation, and the sebum content of the cheek and GPx showed a significant negative correlation. The hydration of the forehead and serum copper showed a significant negative correlation, and the hydration of the forehead and GPx showed a significant positive correlation. The hydration of the chin and serum SOD showed a significant positive correlation. With these results, it is considered that the basic condition of nutritional status can affect the skin health.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book(Dong-ui-bo-gam). Oriental herbs(Angelica daurica, Arctium lappa, Coptidis rhizoma, and Glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay; P. acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acnes. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation or $C^{14}$-acetate in culture media. The $C^{14}$-labeled lipids were extracted and determined by liquid scintilation counting. Coptidis rhizoma markedly inhibited sebum production. 3. Anti-bacterial assay for P. acnes(MIC test); Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis, Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica, Coptidis rhizoma. and Glycyrrhiza glabra is expected to provide effective acne treatment.

Objectives The purpose of this study is to investigate the effects of Gleditsiae Fructus 70% EtOH extract (JS_E) on anti-inflammatory action in HaCaT cells (A spontaneously immortalized human keratinocyte cell line) and inhibiting triglyceride genesis in SEB-1 cells (Immortalized human sebocyte). Methods The anti-inflammatory effect of JS_E was analyzed by enzyme-linked immunosorbent assays (ELISA) which measured levels of IP-10, RANTES and MDC in HaCaT cells. Also the effect on secretion of sebum of JS_E was analyzed by TG-S kit which measured the quantity of triglyceride in SEB-1 cells. Results JS_E inhibited IP-10, RANTES and MDC expression in a dose dependent manner. IP-10 expression was inhibited significantly in comparison to TNF-${\alpha}$ and IFN-${\gamma}$ recombination (TI) control group at concentration of JS_E $200{\mu}g/ml$ and RANTES and MDC expressions were inhibited significantly at concentration of JS_E 100, $200{\mu}g/ml$. JS_E also inhibited triglyceride secretion of SEB-1 cells significantly in comparison to the control group in a dose dependent manner. Conclusions This study shows that JS_E has the effects of anti-inflammatory action and inhibiting sebum secretion. According to these results, JS_E can be used for treating skin diseases such as acne and dermatitis caused by inflammation and excessive secretion of sebum by controlling the activity of the HaCaT and SEB-1 cells.

This study attempted to numerically verify specific effects on skin condition improvement by measuring and comparing changes in skin conditions such as pores, wrinkles, and sebum of LED masks for beauty devices with low output among light sources. 18 healthy women (4 weeks in the control group and 4 weeks in the experimental group) were conducted once a week for 8 weeks. As a result of measuring the skin condition of pores, wrinkles, and sebum, it was confirmed that the skin condition improved significantly as the LED irradiation progressed, and the difference between the groups by measurement period of the experimental group and the control group also showed significant differences in pores, wrinkles, and sebum (p< .001, p<.05). This is meaningful in that it can be presented as clinical information and quantitative data by preparing continuous data in an academic sense by proving the effect of improving the LED mask as a beauty device. It is also suggested that in the future, follow-up studies to prove more effective skin improvement will be conducted.

This study is to propose Lagerstroemia indica flower as an anti-acne cosmetic material, and confirmed the sebum control, anti-inflammatory, and antioxidant effects using Lagerstroemia indica flower extract (LIFE) . As a result of evaluating the sebum control effectiveness, it was confirmed that LIFE inhibited the production of sebum excessively induced with palmitic acid up to 65%. Subsequently, it was confirmed that LIFE has an antibacterial effect and the ability to inhibit lipase activity against Cutibacterium acnes (C. acnes), which mainly appears in acne lesions, and can also reduce the inflammatory response caused by virulence factors secreted by C. acnes. It was also confirmed that LIFE inhibited the secretion of nitrogen monoxide (NO) and prostaglandin E2 (PGE2), which are inflammatory mediators induced by LPS in macrophages, by 75% and 54%, respectively, and that it also had a high DPPH radical scavenging ability similar to that of ascorbic acid. These results suggest that LIFE, a natural extract, can be used as an anti-acne material to relieve and treat acne, a complex disease, by controlling sebum production and having antibacterial and lipase activity inhibiting against C. acnes, and anti-inflammatory, antioxidant properties.
